1. 41. Issues in Urban Travel Demand Modelling : ICT Implications and Trip timing choice

   Författare :Maria Börjesson; Staffan Algers; Kay Axhausen; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Journey; Mathematical model; Origin traffic ; Time; Telecommuting; Journey time; Variability; Stated preference; Delay; Civil engineering and architecture; Samhällsbyggnadsteknik och arkitektur; 11 Road: Personal transport; 11 Road: Personal transport;

   Sammanfattning : Travel demand forecasting is essential for many decisions, such as infrastructure investments and policy measures. Traditionally travel demand modelling has considered trip frequency, mode, destination and route choice. This thesis considers two other choice dimensions, hypothesised to have implications for travel demand forecasting. LÄS MER

3. 42. Linking lake variability, climate, and human activity in Basotu, Tanzania

   Författare :Lindsey Higgins; Lars-Ove Westerberg; Jan Risberg; Sarah Davies; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Tanzania; crater lake; climate change; land-use change; water resources; environmental variability; diatoms; paleolimnology; chronology; Physical Geography; naturgeografi;

   Sammanfattning : Paleoenvironmental investigations establish important baseline knowledge of the natural variability of lake systems, to better understand human impacts on the landscape, and the effects of climate change on water resources. By combining long-term environmental history with investigations into modern land use patterns and climatological events, a wider perspective can be reached that has practical applications in water governance.

4. 43. Probing the Precipitationshed : A quantification of the biophysical dimensions of terrestrial moisture recycling

   Författare :Patrick W. Keys; Line Gordon; Steve Lyon; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; moisture recycling; precipitation; evaporation; variability; ecosystem services; naturresurshushållning; Natural Resources Management;

   Sammanfattning : Terrestrial moisture recycling is the phenomena whereby water evaporates from the land surface, travels through the atmosphere, and fall as precipitation downwind. The interaction of societies with this branch of the hydrological cycle, though critical to the productive functioning of ecosystems around the planet, remains poorly understood. LÄS MER

5. 44. Site variability and settlement patterns : an analysis of the hunter-gatherer settlement system in the Lule River Valley, 1500 B.C.-B.C./A.D

   Författare :Lars L. Forsberg; Umeå universitet; []
   Nyckelord :HUMANIORA; HUMANITIES; Hunter-gatherers; intrasite patterning; multivariate analysis; resource exploitation; settlement patterns; site function;

   Sammanfattning : This thesis deals with questions concerning prehistoric hunter-gatherer society on the River Luleälv in Northern Sweden from c. 1500 B.C. to B. LÄS MER

7. 45. Grammatical correctness and communicative ability : a performance analysis of the written and spoken English of Swedish learners

   Författare :Inger Bergström; Umeå universitet; []
   Nyckelord :HUMANIORA; HUMANITIES; grammatical correctness; communicative ability; performance analysis; written and spoken English; classroom instruction; low-achievers; language learning; interlanguage; compensatory strategies; errors; verb phrase; parameters; systematicity; variability; writing proficiency; speech proficiency; elicitation test;

   Sammanfattning : Written and oral material produced by a group of low-achieving learners of English from the 2-year lines of the Swedish upper secondary school was analysed from the perspective of grammatical correctness and communicative ability. The grammatical analysis focussed on the verb phrase and tests included both free production in speech and writing and elicitation tests. LÄS MER
